Ftwalk is a high-level script programming language that is very similar to AWK but greatly extended to include a richer type system, object-oriented features, 300+ built-in functions and extensibility through dynamic libraries, which makes it roughly comparable to languages like Perl. It does file tree searches, and it was originally used to implement selective redundant copy backup stores. It can be run interactively as a calculator.
